This frame is made of top quality steel and deformed aluminum alloy and treated with galvanizing, oxidation and electrostatic plastic spraying. The frame has solid structure and pleasing appearance.

- Fully-closed structure with the advantages of good performance of dust-proof, pleasing and neat appearance.
- Enough space for fiber distribution and storage space and very easy for installation and operations.
- Fully front side operation, convenient for maintenances. Curvature radius of 40mm.
- Mini integrated splice and distribution unit is adopted for saving spaces, which enable large capacity in the limited dimensions. Each unit holds up to 12 FC/SC adapters. All units have specially designed slots and can be easily pulled out for operation at any time.
- Fiber separation hook of the mini splice and distribution unit (the hook on the left or right) can be disassembled to fit for both wide and narrow structure frame.
- Every 6 units make up a module.
- All adaptors are installed 40 degrees inclining to the operation surface which is easier for connecting and also protect installers,eyes from the lights.

- Working with wavelength of 850nm, 1310nm and 1550nm
- Insertion Loss: ≤ 0.30dB
- Return Loss: ≥ 0.45dB (PC)
- Pressurization between the frame high voltage protection earth device and the frame ≥3000V(DC) for 1 minute without any breakdow or flashover.
- Insulation resistance between the frame high voltage protection earth device and the fram ≥1000MΩ/500V(DC).
- Mechanical durability: No damage for all connectors and adaptors after 500 mating times.
